Global LED Lighting Drivers Market Analysis , Size , Share , Growth and Forecast to 2021- Hexa Research
“ Key driving factors responsible for the growth of global LED lighting drivers market includes growth in demand of LED in lighting applications and rapidly growing usage within the commercial applications .
In light bulbs , light is generated by a tungsten wire which only converts a small portion of energy into visible light . This principle was followed for many years due to its simple structure & pleasant light . LED lights although have a higher luminous efficacy than light bulbs , luminaires were not considered as a replacement for light bulbs . So , in comparison to light bulbs LEDs need special attention on the power source which means , if LED ’ s are insufficiently supplied with energythe light keeps flickering or is perceived as choppy .
Special circuits are necessary to convert the mains voltage to a precisely matching voltage for connected luminaire . These circuits are power supplies mainly optimized for LED ’ s and are basically known as LED Lightning drivers . Increasing energy regulations and other factors are now resulting into energy savings associated with LED ’ s . LED requires driver mainly to run on a low voltage and direct current electricity ; and also LED driver rectifies higher voltage , alternating current to low voltage and direct current . LED drivers also protect LED ’ s from voltage or current flickers . Change in voltage causes a change in current being supplied to the LED ’ s . Hence , too much or too little current can cause light output to vary or degrade rapidly owing to higher temperatures within the LED .
At a glance , LED drivers convert higher voltage , alternating current to low voltage , direct current and LED drivers keep the voltage & current flowing through an LED circuit at its standard leve l . Also , it is important to make a wise selection between constant-current drivers , constant-voltage drivers and AC LED drivers .
